Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double glazing having an attachment.

[0002]

2. Description of the Related Art The usage rate of double glazing has been increasing from the viewpoint of energy saving and soundproofing, but the double glazing is attached to a sash by winding a glazing channel or by sealing with a backer. Is common. 4 and 5 exemplify the case of the former glazing channel, in which the glazing channel 9 is wound around the left and right and the upper edge of the double glazing 2, and the upper frame 6
Also, the lower frame 7 is fitted to the mounting openings of the left and right frames 8 and is attached to the lower frame 7 by the bead 10.

[0003]

In such a mounting method, operations such as winding the glazing channel around the periphery of the double glazing, cutting the corners and abutting the glazing channels are required, which requires a great number of steps. In particular, since double glazing has a larger total thickness than ordinary glass, it takes a lot of time and effort to wind the glazing channel during assembly.

Further, since these glazing channels and beads inevitably have many exposed portions exposed to the outside air, replacement is necessary because the glazing channels and the like shrink or crack due to aging after construction.
The latter sealing method not only takes more time and labor for the on-site sealing work, but there is a concern that the seal may be broken after the construction.

As described above, in the conventional structure for mounting double glazing, the glazing channel and the sealing material are interposed between the double glazing and the shoji sash, which requires a lot of man-hours for assembly and requires maintenance after the construction. There are drawbacks such as.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an alternative to glazing channels and seals and improvement in workability and quality. Specifically, the function of the glazing channel or the sealing material is integrated in the double glazing, and in order to easily and easily incorporate the double glazing, the glazing attachment is added to the double glazing. .

That is, according to the present invention, a channel-shaped reinforcing material that can surround the peripheral portion of the double glazing, an internal soft material provided on the inner surface of the reinforcing material facing the double glazing, and an outer material that engages with the sash are provided. It is characterized in that an attachment made of an external soft material provided on the side surface is attached to the peripheral portion.

In the present invention, a metal, a synthetic resin or the like can be used as the reinforcing material, but a metal such as aluminum, steel or stainless steel is usually used.
Considering the corrosion resistance, aluminum is most preferable.
These reinforcing materials have a U-shaped cross section when applied to the double glazing and surround the peripheral edge of the double glazing.
Then, in the case of a metal reinforcing material, it is bent into a U-shaped channel before or after forming the inner and outer soft materials, and by fitting the edge portion of the double glazing into the U-shaped opening, It can be easily attached to double glazing. On the other hand, in the case of a synthetic resin reinforcing material, it may be bent when it is adhered to the peripheral portion of the double glazing.

In the present invention, as the inner soft material and the outer soft material integrally provided on the inner and outer surfaces of the reinforcing material, vinyl chloride resin or acrylic resin has a Shore A hardness of 60 to 7
Most preferred is about 0 °. The selected soft material is
The inner surface of the reinforcing material facing the double glazing and the outer surface of the reinforcing material that engages with the shoji frame or sash are partially or entirely formed continuously and integrally. In this case, the shape of these soft materials is not particularly limited, but the external soft material attaches and fixes the double glazing to the shoji frame or the like so that the glass is firm and watertight, and especially the edge exposed to the outside is It is good to devise it to be as small as possible.

[0010]

1 and 2 show a general embodiment of the present invention, in which an attachment 1 mainly composed of a reinforcing material 5 made of aluminum is provided at the peripheral portion of the double-glazing unit, It is fitted and attached to each side of, to facilitate mounting and assembling to the sash frame.

An inner soft material 4 made of, for example, vinyl chloride resin is continuously provided in the longitudinal direction on the inner surface of the reinforcing material 5 having a U-shaped cross section. The main function of this internal soft material is to prevent the reinforcing material 5 from directly contacting the glass. Normally, the inner surface of the channel-shaped reinforcing material 5 facing the glass is projected at a predetermined interval in the longitudinal direction. It may be formed as a piece. In this way, it is possible to prevent the sash frame of the double glazing from coming off from the mounting opening.

On the other hand, an outer soft material 3 of the same material is integrally fixed to the outer surface of the reinforcing material 5. In this case, the form of the outer soft material 3 is not particularly limited, but when the double glazing with the attachment is fitted to the frame or the sash,
It is necessary to ensure sufficient water tightness. In the illustrated preferred embodiment, the outer soft material is integrally formed on the outer surface of the channel-shaped reinforcement 5, and a part of the outer soft material covers the open end of the reinforcement 5, and the lip of the outer soft material forms the glass. Can be sealed.

The multi-layer glass with the attachment can be obtained by applying the attachment 1 to the peripheral portion of the multi-layer glass 2. This deposition may be carried out on the spot prior to mounting the double glazing on the frame or sash, but it is usually preliminarily mounted on the double glazing in a separate step.

That is, the attachment 1 is cut to fit the peripheral dimensions of the double glazing 2, and then the edge of the double glazing is fitted into the opening of this attachment. This attachment is fixed to the peripheral edge of the double glazing by an appropriate friction between the lip of the inner soft material 4 and the outer soft material 3 and the glass.

FIG. 2 shows a state of the lower frame 7 when the multi-layer glass with the attachment shown in FIG. 1 is attached to a frame or the like. A block 8 is laid at the bottom of the mounting opening of the lower frame 7 to support the lower end of the double-glazing, and is firmly clamped by the lower frame from both sides of the attachment via the external soft material 3. Reference numeral 11 in the figure denotes a hole provided in the block 8 for draining rainwater that has entered the lower frame.

FIG. 6 shows a double-layer glass with an attachment in which the external soft material has another preferable form. In this example, the external soft material 3 has a locking portion 13 to the tip edge 17 of the mounting opening of the sash frame. This locking portion 13
By being locked to the upper edge 17 of the sash frame, the end face of the double glazing with the attachment can be fixed at a predetermined position in the mounting opening of the frame. In this way, even when an external force is applied to the double glazing 2 and the attachment or the like, the double glazing does not go deep into the mounting opening of the frame, and the double glazing can be prevented from shifting in the sash. This is particularly effective when the block is not inside the mounting opening of the frame, such as the upper frame and the frame.

The reinforcing material 5 is preferably provided with drainage holes 20 so as to be scattered in the longitudinal direction of the reinforcing material 5, as shown in FIG. This is effective when the double glazing with an attachment is attached to the lower frame, and when water such as rainwater enters through the double glazing and the internal soft material or between the double glazing and the attachment, etc. This is because it is possible to prevent the end face of the double glazing glass from being exposed to moisture for a long time. Further, as shown in FIG. 6, the inner soft material 4 is provided on the reinforcing material 5 so as not to come into contact with the spacer of the double glazing 2, so that the deterioration of the double glazing due to the rainwater or the like and the fogging of the double glazing may be caused. It is effective for prevention.

FIG. 3 shows another embodiment of the present invention, in which the attachment 1 is generally flat as a whole by providing a folding groove corresponding to the thickness of the double glazing, but the attachment 1 can be easily formed. The reinforcing material 5 is formed of a hard synthetic resin that can be bent, the inner soft material 4 and the outer soft material 3 are provided on the inner and outer surfaces of the reinforcing material after bending, and the inner surface and the selected area are double-sided. An adhesive tape 12 or an adhesive layer is provided.

In the double-layer glass with attachment, the reinforcing material is bent from both sides in a state where the attachment is pressed against the edge of the double-layer glass, and the double-sided adhesive tape adheres to the glass surface.

[0020]

As described above, according to the present invention, since the attachment is adhered to the peripheral portion of the double glazing as described above, it can be mounted on the sash frame as it is, compared with the conventional glazing channel method or sealing method. The workability of assembling the sash frame and glass is greatly reduced.

Further, since the soft material is fixedly integrated with the attachment, contraction of the soft material is prevented, the quality after assembly is stable, and gaps at the corners can be prevented.

Further, since the soft material of the attachment is stopped on the upper surface of the sash frame, the area of the soft material exposed to the outside can be reduced as compared with the conventional method, so that shrinkage and cracking due to the influence of sunlight can be prevented. Can be prevented or reduced.
